Health care service plans, self-insured employee welfare benefit plans, and multiple employer welfare arrangements may not refuse to enroll any person, refuse to accept or renew a subscriber, charge a higher rate, or offer different terms, conditions or benefits on the basis of genetic characteristics that may be associated with disability in that person or that persons offspring. A plan may not seek information about genetic characteristics for non-therapeutic purposes. Specific penalties are set forth for violations by self-insured employee welfare benefit plans and multiple employer welfare arrangements.
